I-Cummins B4.5 B6.7 L9 Injini ye-Diesel Dibana ne-Euro VI Emission Standard

I-Cummins ngoku izakuthatha elinye inyathelo malunga nolawulo lokukhutshwa kwe-Euro VI.Idizili ezicocekileyo ngoku ziya kuphendula kummiselo ongqongqo weSigaba-D, emva kophuhliso lweminyaka emibini kunye nenkqubo yovavanyo.Iinjini ze-B4.5, B6.7 kunye ne-L9 ezinoluhlu lwe-112 ukuya ku-298 kW kwizicelo zebhasi kunye nomqeqeshi ziya kuhamba kwimveliso epheleleyo ngaphambi kokuba iSigaba-D siqalise ukusebenza ngoSeptemba walo nyaka.

Iinjini ze-Euro VI Phase-D zokukhutshwa okuphantsi kunye nokuphantsi

Cummins yazisa le ngcamango intsha yokukhupha izinto ezikhutshwayo kwiNgqungquthela yeHlabathi yezoThutho zikaRhulumente ye-UITP eqhubeka eStockholm, eSweden.Iinjini ze-Euro VI Phase-D ziya kuphumeza ukukhutshwa kwemizi ekufutshane ukuya ku-zero.Oku kubonisa inyathelo elongezelelekileyo kwimigaqo ye-Euro VII, eya kuthi mhlawumbi iqalise ukusebenza emva kwe2025.

Imimiselo yeSigaba-D ibaluleke kakhulu kwimisebenzi yebhasi, njengoko igxininisa kwimida yolawulo olungqongqo lwe-Oxides ye-Nitrogen (NOx) ekhutshwayo ngexesha lemisebenzi yedolophu enesantya esisezantsi, kunye naphantsi kweemeko zokuqalisa injini ebandayo.Ukongeza kwi-emissions test test verification, imimiselo yeSigaba-D ifuna uvavanyo olusendleleni ukuze lubambe umlinganiselo wehlabathi lokwenyani.Uvavanyo olusekelwe kwi-Duty cycle-based olwenziwa yi-Cummins usebenzisa i-Portable Emissions Measurement Systems (PEMs) ibonise ukunciphisa ipesenti ze-25 kwi-NOx emissions, xa kuthelekiswa neenjini zeSigaba-A xa i-Euro VI yaziswa okokuqala kwi-2015.

U-Ashley Watton, uMlawuli waseCummins kwi-On-Highway Business Europe, uthe: "Ngokukhutshwa kwe-NOx ephantsi kakhulu, iimveliso zethu zamva nje zeSigaba-D ziya kunceda iinqwelo zeebhasi ziphucule umgangatho womoya kwaye zihambelane nokufika kwamva nje kweLondon Ultra Low Emission Zone kunye nezinye ezicocekileyo. Iindawo zomoya zisekwe kwizixeko kulo lonke elaseYurophu.

Ukufezekisa isiqinisekiso seSigaba-D sigxininise kwingqiqo yokulawula ukukhutshwa kunye nokuphuhlisa i-algorithm entsha yenkqubo yokulawula.Ngokucokisa kunye nokuphinda sivavanye isoftware kwithuba leminyaka emibini, siye sakwazi ukunqanda ukwenza naluphi na utshintsho lwehardware kwi-injini okanye ukukhupha emva konyango.

Umsebenzi wophuhliso lweSigaba-D ufuna utyalo-mali olukhulu nguCummins, kodwa oko kuthetha ukuba abathengi bethu bagcina inzuzo yemveliso eqinisekisiweyo esebenza ngokufanayo naleyo bayifumanayo namhlanje.Ngokumalunga nokudityaniswa kwesithuthi, oku akukho mfuneko yokuphinda wenze ukufakelwa kwe-Euro VI njengoko iinjini zethu zeSigaba-D zinika isisombululo esingenamthungo, sokuhla".

Inqanaba D kwakhona leenguqulelo ezixubileyo

Isiqinisekiso seSigaba se-D siya kunabela kwiinguqulelo ezilungelelanisiweyo zeCummins B4.5 kunye ne-B6.7 yeenjini, ukunceda abavelisi beebhasi kulo lonke elaseYurophu kwindlela eya ekufakeni umbane kunye ne-decarbonization yezithuthi.Kunye ne-diesel-electric driveline, i-4.5- kunye ne-6.7-litha ye-diesel ecocekileyo inokunciphisa ukusetyenziswa kwamafutha kunye nokukhutshwa kwe-CO2 malunga neepesenti ezingama-33.

Kwiindlela eziqhelekileyo zokuqhuba ibhasi yedizili, iinjini zeCummins ezinetekhnoloji yokumisa/yokuqalisa nazo ziya kuhambela phambili kwiSigaba-D, ukonga amafutha kunye nokukhutshwa kwerhasi yegreenhouse ngokuphantse kuphelise ukusebenza kwe-injini kwiindawo zokumisa iibhasi.

Uphuculo oluqhubekayo lwe-Euro VI

Ukususela ekuqaleni kweSigaba-A ukuqaliswa kwemigaqo ye-Euro VI, Iijenereyitha ze-injini yeCummins ibone iinguqu eziqhubekayo ukuhlangabezana neZigaba ezilandelelanayo ngobuchwepheshe obunye nobutsha bolawulo lokukhutshwa kwezinto ezikhutshwayo.Iinjini ze-Phase-C zangoku, eziveliswe ngo-2016, nazo zaphuculwa ngemveliso yamandla eyongeziweyo kunye ne-torque.

I-4-cylinder B4.5 ekhupha ukuya kuthi ga kwi-157 kW iphucule ukusabela kwesithuthi ngokunyuka kwe-torque ephantsi kunye ne-peak torque ukusuka kwi-760 ukuya kwi-850 Nm.I-6-cylinder B6.7 inyuse izinga eliphezulu ukuya ku-220 kW kunye ne-torque ephezulu inyuke ukuya kwi-1,200 Nm ku-1,000 rpm.Ixabiso eliphezulu lebhasi le-L9 linyuke ukusuka kwi-239 ukuya kwi-276 kW ngokunyuka kwe-torque ephezulu ukuya kwi-1600 Nm.
